Teslong Rifle Borescope With 4.5 Inch Screen
This model targets rifle inspection with a close-focusing sensor and a 4.5-inch color IPS display. It supports viewing and recording at 1920×1080 resolution and stores data on a 32GB micro SD card included with the kit. The 0.2-inch probe diameter allows entry into barrels as small as .20 caliber, and the 36-inch flexible camera probe gives full coverage from chamber to muzzle. It’s designed for Windows PC or Android devices, but not iOS, which is important for users in Apple ecosystems to consider.
Key considerations include ease of use and immediate feedback on cleaning effectiveness. The device is plug-and-play, meaning users can avoid complicated apps or software installations. For shooters who want a portable, self-contained inspection solution, this model offers a solid balance of image quality, ease, and portability. If you prioritize a handleable size and a robust probe, this option is worth evaluating against higher-screen alternatives.
Teslong Rifle Borescope, 3 Right-Angle Mirrors
This Teslong kit emphasizes thorough bore visualization with a 45-inch flexible probe and three right-angle mirrors. It fits calibers as small as .20 and provides tools to inspect throat erosion, rifling wear, and fouling. The kit is compatible with Windows, Android (OTG-enabled), and Mac, but it is not designed for iPhone or iPad. The mirror set expands viewing angles, helping to reveal obstructions or wear that straight-line viewing might miss. The balance between probe length and multiple viewing angles makes this a strong pick for precise inside-bore assessment.
Users should note the requirement for OTG compatibility on Android devices and the absence of iOS compatibility. For shooters who value flexibility in viewing angles and a long, flexible insertion probe, this model serves well as a primary inspection tool or as a companion to a rigid bore scope in mixed rifle setups.
Teslong Borescope With 5″ Monitor
This firearm inspection package centers on a 5-inch IPS screen with a 45-inch flexible probe. The built-in 3500mAh battery supports cordless use, and the device does not require a phone connection to view images and video. The 0.2-inch diameter probe remains compatible with rifles of .20 caliber and larger, enabling detailed inspection of cleanliness, throat erosion, tool marks, and rifling wear. The system is designed to be ready out of the box, which reduces setup time for range or field use.
Considerations include battery life and screen size, which affect how long you can inspect a barrel in one session and how easily the image can be reviewed during maintenance planning. For users who want a balance of independent viewing capability and portability, this 5″ model offers a convenient, reliable option for routine bore checks and maintenance planning.
Teslong Rigid Rifle Borescope With 5″ Monitor
This is a 26-inch rigid insertion tube option with a 5-inch IPS screen, designed for stable handling during bore inspections. The rigid probe minimizes wobble, which helps shooters place the camera at precise inspection points and measure wear or fouling with greater accuracy. The kit includes close-focusing optics to detect cleanliness issues and is compatible with Windows, Mac, and Android devices via USB/Micro-USB, though it does not support iPhone or iPad due to compatibility constraints.
Users should weigh the benefit of a longer, rigid insertion length against the flexibility of a flexible probe. If your rifles require extended reach to inspect the full length of the bore without repositioning, this model offers a clear advantage. It is a strong choice for guns with longer barrels or for technicians who need consistent image angles during inspection sessions.
Teslong Rifle Borescope For Phone & PC, USB C
This model introduces a USB-C upgrade to support iPhone 15/16 and USB-C Android devices, while preserving the original USB and Micro-USB connections for Windows and Mac compatibility. The 0.2-inch diameter probe fits calibers down to .20, enabling inspection for cleanliness, throat erosion, tool marks, rifling wear, and fouling. The kit includes six mirrors for multi-caliber barrels, including five 45-degree mirrors and a 35-degree mirror to reduce glare on the bore wall. This versatility makes it a strong multi-caliber option for enthusiasts and professionals who maintain a variety of rifles.
Key factors include device compatibility and accessory breadth. For owners who prefer to connect to newer smartphones or tablets via USB-C while still retaining computer compatibility, this borescope provides a broad connectivity set and mirrors that help manage glare and obstructions in the bore while inspecting complex rifling patterns.
Teslong Rifle Borescope For Phone & PC, USB C (NTG100-C)
The NTG100-C version emphasizes USB-C support for direct connection to iPhone 15/16 and USB-C Android devices, while maintaining compatibility with Windows and macOS through standard USB or Micro-USB cables. It features a 0.2-inch micro-probe with 5mm mirrors to cover calibers from .20 to .50, along with five standard 45-degree mirrors and a 35-degree mirror. By offering a USB-C-centric design, it caters to users who prioritize streamlined, modern device connectivity for field use and maintenance checks.
Buyers should assess whether they primarily inspect with a phone or a PC, and whether USB-C compatibility is a priority in their setup. The included mirrors support a wide caliber range, making this model suitable for multi-caliber rifles and workshop environments where various barrel profiles are common.
Buying Guide: Key Purchase Considerations
- Caliber compatibility: Most Teslong borescopes cover .20 caliber and larger; verify the smallest bore you intend to inspect to ensure fit.
- Probe length and rigidity: Longer probes reach deeper into longer barrels, but rigid tubes offer steadier images. Flexible probes are better for navigating curves; rigid ones excel in straight sections.
- Screen size and power: Larger screens enhance visibility but add bulk. Battery-powered models offer field independence, while USB-connected variants rely on an external device for display.
- Compatibility: Consider whether you need iOS support or USB-C compatibility for modern devices. Android OTG support is essential for some models.
- Mirrors and accessories: A wider set of mirrors enables viewing at different angles and calibers. Carrying cases and extra memory (SD cards) improve field usability.
- Image quality and storage: Look for 1080p or higher resolution, with the ability to record video and capture stills. Memory cards should be included or easily accessible.
- Ease of use: Plug-and-play setups reduce setup time in the field. Consider models that don’t require software installs or driver downloads.
- Maintenance implications: Regular use of a borescope can shorten downtime by enabling faster diagnosis of wear and fouling before failures occur.
When selecting among these models, buyers should balance screen size, cable length, and device compatibility against their rifle collection and inspection workflow. A combination of a larger-screen handheld unit and a flexible, multi-mirror kit often yields the best coverage for diverse calibers, from small-bore rifles to larger hunting firearms. For users who need the newest device compatibility, USB-C enabled models offer future-proof connectivity to modern smartphones and tablets, while still supporting PC use where needed.
